Sand tiger foetuses ‘eat each other in utero, acting out the harshest form of sibling rivalry imaginable’. Only two babies emerge, one from each of the mother shark’s uteruses: the survivors have eaten everything else. ‘A female sand tiger gives birth to a baby that’s already a metre long and an experienced killer,’ . . . .A new book, Demon Fish, receives an approving review from Theo Tait in the London Review of Books. Tait muses over our disproportionate reaction to the shark danger:
Even in the US, a global hotspot, you are forty times more likely to be hospitalised by a Christmas tree ornament than by a shark. Meanwhile, to supply the shark fin soup trade alone, an estimated 73 million sharks are killed each year. Many shark populations have declined by 70 per cent or more in the last thirty years.Sure, tell that to my amygdala. As the reviewer concedes, they're down there below the surface, and they eat us alive. My amygdala doesn't find Christmas ornaments daunting in the least. No one's going to make a fortune directing a blockbuster movie about people that stab themselves with glass icicles, or whatever it is they do to put themselves into hospitals at Yuletide (sounds like there's an untold story there).
